Qelbree vs Adderall: What's the difference between them?

Overview

Qelbree (viloxazine ER) and Adderall (mixed amphetamine salts) are both oral medications used to treat attention deficit hyperactivity disorder (ADHD) in adults and children. Qelbree is used in adults and children 6 years of age and older, while Adderall is used in people 3 years and older.

• The main differences are that Qelbree is a long-acting, once daily nonstimulant medicine and is not classified as a federally controlled substance. It is less likely to cause trouble with sleeping or lead to abuse. In studies, Qelbree has not been shown to lead to withdrawal symptoms or dependence.
• Adderall is a short-acting stimulant medication given once or twice a day, and is a C-II controlled substance with the potential for misuse, drug dependence, and illicit distribution to others. The amphetamines in Adderall are dextroamphetamine saccharate, amphetamine aspartate, dextroamphetamine sulfate, and amphetamine sulfate.

Common side effects that Qelbree and Adderall share include upset stomach (nausea, vomiting, stomach ache) and decreased appetite. Qelbree is more likely to cause drowsiness and headache, while Adderall may be more likely to cause trouble sleeping, weight loss or drug abuse or diversion.

Other differences:

• Dosing: Qelbree is given once per day as an oral capsule, and Adderall is usually given 1 to 3 times a day as an oral tablet. Adderall XR is available as a once-daily option.
• Adderall is also approved by the FDA to treat the sleep disorder narcolepsy in adults and children 6 years and older. Other brand names for mixed salts of amphetamine and dextroamphetamine include Adderall XR (a long-acting form) and Mydayis. Qelbree is only approved for ADHD.
• Adderall is available as a generic product in the US, which may help save you money. Qelbree is the more expensive product and does not have an approved generic option at this time.

What is ADHD?

Attention deficit hyperactivity disorder, or ADHD, is a common condition marked by ongoing issues related to attention, hyperactivity, and impulsiveness that can interfere with learning, development and daily functioning. It can occur in school aged children and adolescents and often persists into adulthood. In the U.S., just over 9% of children and up to 5% of adults are estimated to have ADHD.

ADHD medicines should be used as part of a total treatment program for ADHD that may include counseling or other therapies. Behavioral treatments usually are recommended for preschool-aged children.

Do Qelbree and Adderall work the same way?

No. Qelbree is in the drug class known as selective norepinephrine reuptake inhibitors. These products prevent the reuptake of norepinephrine (a brain neurotransmitter) to improve focus and attention in patients with ADHD. It is not a stimulant and has not been shown to have a risk for abuse or drug dependence.

Adderall is a central nervous system (CNS) stimulant that raises the neurotransmitter levels of dopamine and norepinephrine in the brain. This can help control hyperactivity, impulse control and increase attention. Adderall is a controlled substance and may have a risk for abuse or drug dependence.

Boxed Warnings

Both agents contain a Boxed Warning, the FDA’s strongest warning for safety and side effects, some of which may be life-threatening, but the warnings differ. It is important to discuss these possible side effects with your healthcare provider.

• Qelbree (viloxazine ER) contains a Boxed Warning for an increased risk of suicidal thoughts and actions in some children and adolescents with ADHD, especially within the first few months of treatment or when the dose is changed. Patients should be carefully monitored, and any new or sudden changes in mood or behavior should be reported right away to your healthcare provider.
• Adderall (mixed salts of amphetamine and dextroamphetamine) contain a Boxed Warning for a high potential for drug misuse due to the fact this drug is a stimulant. Amphetamines given for prolonged periods may lead to drug dependence and must be avoided. People may try to obtain amphetamines for non-therapeutics uses or to distribute to others. This medicine should be prescribed or dispensed sparingly. Misuse of amphetamine may cause sudden death and serious cardiovascular (heart) side effects.

BOTH products also contain a warning for a dangerous drug interaction with MAOIs.

DO NOT USE Qelbree or Strattera if you are taking or have taken within the past 14 days an anti-depression medicine called a monoamine oxidase inhibitor or MAOI. Combined use may lead to side effects that could be deadly.

• MAOIs are an older class of drug used to treat severe depression and other mental health disorders.
• MAO inhibitors include medicines like isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, tranylcypromine, and others.
• Ask your healthcare provider or pharmacist if you are not sure if you or your child takes an MAOI.

Be sure your doctor or pharmacist screens for drug interactions with any medicines you take, including prescription, over-the-counter (OTC), vitamins, and herbal or dietary supplements.

Do not start or stop any new medicine during treatment without first talking to your healthcare provider. Your doctor can decide if it is safe for you to combine medicines.

Do not use Qelbree if:

• you take any of these drugs: alosetron, duloxetine, ramelteon, tasimelteon, tizanidine, or theophylline.

Do not use Adderall (or generic: mixed salts of amphetamine and dextroamphetamine) if you or your child:

• are allergic or sensitive to Adderall or other stimulant medicines
• have heart disease or hardening of the arteries
• have moderate to severe high blood pressure
• have hyperthyroidism
• have glaucoma (an eye disease)
• are very anxious, tense, or agitated
• have a history of drug abuse

Serious side effects: Stimulants like Adderall can cause a stroke, heart attack, and sudden death in people with high blood pressure, heart disease, or a heart defect.

Always review the Patient Medication Guide for any new information each time you get a prescription filled. Your pharmacist can give you a Medication Guide if you do not have one.

Which is more effective, Qelbree or Adderall?

Head-to-head, randomized, comparative studies between Qelbree with Adderall are not available, so it is not possible to say which one is more effective. They both have been shown to be effective options for treating ADHD in studies when compared to a placebo (a pill with no active ingredient).

Initially, stimulants like Adderall or Ritalin (or generic equivalents) are considered the gold standard for treating ADHD symptoms. They are often recommended for first-line treatment, when possible, in guidelines. However, effectiveness can vary among individuals and some people may have better results with the nonstimulants or tolerate the side effects better.

In clinical studies, both Qelbree and Adderall have been shown to be effective in the treatment of ADHD in adults and children. Selection of one product over the other may depend upon your preference or that of your healthcare provider, concern over side effects, a history of drug abuse or misuse, and cost.

Approval for Qelbree was supported by data from Phase III randomized, placebo-controlled studies of over 1,000 children 6 to 17 years of age. Doses studied were 100 mg, 200 mg, or 400 mg per day, with treatment duration of 6 to 8 weeks. The primary efficacy measure, the change in the ADHD-RS-5 Total Score from baseline, was met statistically for all doses.

Nonstimulants like Qelbree or Strattera may be selected agents for treatment of ADHD for patients when substance abuse is a concern, either for the patient or family. Nonstimulants may also be preferred for children with tics, Tourettes or who have had previous severe side effects with stimulants.

Your doctor may decide to combine a nonstimulant with prescription stimulants, or use a nonstimulant when stimulants cannot be used, have been ineffective, or are not well-tolerated.

It is important to remember that research shows that ADHD stimulant treatment decreases the risk of substance abuse and may delay the onset through adolescence (although risks may still be present in the house with family members or friends). Adolescents with ADHD have also been shown to have fewer car accidents when being treated for ADHD compared to those who are not treated.

In addition, for children under the age of 6, Parent Training in Behavior Management (PTBM) and / or behavioral classroom interventions are the first line of treatment. The use of medications, with or without PTMB, are the first-line therapy for school-aged children (≥6 years) and adolescents who meet diagnostic criteria for ADHD.

Bottom Line

• Qelbree and Adderall are both oral medications that are effective in treating ADHD in children and adults. Qelbree, a nonstimulant, is classified as a selective norepinephrine reuptake inhibitor and Adderall is a CNS stimulant (a mixed amphetamine salt).
• Qelbree is an extended-release capsule given once per day, while Adderall is an oral tablet given 1 to 3 times per day depending upon patient needs. Both products can be taken with or without food.
• Adderall is available as a generic option, but Qelbree is only available as a brand name product at this time, which makes it more expensive. Insurance is more likely to pay for Adderall due to the generic availability.
• Adderall is a controlled substance and is associated with misuse, abuse and drug dependence, but Qelbree is not a controlled substance.
